Micropropagation is a powerful tool for large-scale propagation of ornamental plants. Modern techniques have been developed to meet the demands of the cut flower industry in the next century. An overview on the in vitro propagation via meristem culture and somatic embryogenesis is covered. Genetic transformation technique has significantly simplified the breeding procedures and overcome some of the agronomic and environmental problems, which otherwise would not be achievable through conventional methods. The development and remarkable achievements in ornamental plants made during the last three decades with biotechnology have been reviewed. The usefulness of ornamental plants in commercial industry as well as propagation techniques is also discussed.
